DNA Replication

Monomers of DNA and RNA are called...

• Proteins

• Amino Acids

• Nucleotides

• Nitrogen Bases

Which of the following is not a component of a nucleotide?

• Nitrogen Base

• Phosphate

• Pentose Sugar

• Disulfide Bridge

What type of bond hods together the sugar of one nucleotide and the phosphate of the next nucleotide in the backbone of a molecule of DNA?

• Hydrogen

• Covalent

What type of bond hods together the nitrogen base of one nucleotide and the nitrogen base of the nucleotide on the complementary strand of DNA?

• Hydrogen

• Covalent

Provided evidence that bacteria could undergo transformation. DNA could be transferred from one bacterial cell to another, which would in turn change the phenotype of the cell.

• Chargaff

• Griffith

• Messelson/Stahl

• Hershey/Chase

• Watson & Crick

Provided evidence that DNA is responsible for carrying the genetic information in a cell, not proteins.

• Chargaff

• Griffith

NGSS.HS-LS3-1

Provided evidence that although base composition may vary between species, the number of Adenine bases in a given species is usually equal to the number of Cytosine bases.

• Chargaff

• Griffith

• Messelson/Stahl

• Hershey/Chase

• Watson & Crick

A given fragment of a DNA molecule is composed of 200 base pairs. 40 of them are Cytosine. How many Thymine bases would you expect to find within the molecule?

• 40

• 60

• 120

• 160
